create a project and in it a class with a main.

We will be using the Scanner class to read from the user. At the top of your main class, after the package statement, paste

import java.util.Scanner;

Part A

☑ In your main method, paste this code.

         Scanner scan = new Scanner(System.in);
        System.out.println("What is x?");
        int x = scan.nextInt();
        System.out.println("What is y?");
        int y = scan.nextInt();
        System.out.println("What is z?");
        int z = scan.nextInt();
        System.out.println("What is w?");
        int w = scan.nextInt();
        
        boolean happy;
        boolean dead;
        
        System.out.println("Are you happy (y/n)?");
        String userhappy = scan.next();

        System.out.println("Are you dead (y/n)?");
        String userdead = scan.next();

☑ After this, if what they enter for userhappy is "y" set happy to true, otherwise to false.

Do the same again to set a value for dead, so that we can better serve our zombie users.

☑ Write single if statements using boolean operators to do as follows:

  • if x, y, and z all have the same value and the user is happy then print "Same and happy"
  • if w is over 12 and the user is both happy and alive then print "Over 12, happy, alive"
  • [EC+10] if x is less than z and both w and y are in the range between x and z, and either the user is happy and dead, or sad and alive then print "Long expression is . . . long"

CODE FOR THE FOLLOWING PROGRAM:-


import java.util.Scanner;
public class Main
{
        public static void main(String[] args) {
            Scanner scan = new Scanner(System.in);
        System.out.println("What is x?");
        int x = scan.nextInt();
        System.out.println("What is y?");
        int y = scan.nextInt();
        System.out.println("What is z?");
        int z = scan.nextInt();
        System.out.println("What is w?");
        int w = scan.nextInt();
        
        boolean happy;
        boolean dead;
        
        System.out.println("Are you happy (y/n)?");
        String userhappy = scan.next();

        System.out.println("Are you dead (y/n)?");
        String userdead = scan.next();
        
        //If user is happy assign happy to true
        if(userhappy.compareTo("y")==0){
            happy=true;
        }else{
            happy=false;
        }
        
        //If user is dead assign dead to true 
        if(userdead.compareTo("y")==0){
            dead=true;
        }else{
            dead=false;
        }
        System.out.println(happy);
        
        //if x, y, and z all have the same value and the user is happy then print "Same and happy"
        if((x==y && y==z) && (happy==true)){
            System.out.println("Same and happy");
        }
        
        //if w is over 12 and the user is both happy and alive then print "Over 12, happy, alive"
        if(w>12 && happy==true && dead==false){
            System.out.println("Over 12, happy, alive");
        }
        
        if(x<z){
            if((w>x && w<z) && (y>x && y<z)){
                if((happy==true && dead==true) || (happy==false && dead==false)){
                    System.out.println("Long expression is . . . long");
                }
            }
        }
        }
}
